If you don't have stories anymore, it means that you have already reached the last game level. On the last game level there won't be new stories and café tasks, but in the future when the new levels are added to the game, the new stories and café tasks will become available for you.
 
If there are no stories, and your game level is too far from the last one, no worries, it is also ok. Now the stories are no longer linked to the exact game levels as it was before, and therefore on some levels you may not have them. In this case, you just need to complete café tasks, earn experience points, and when you go to the next level, the new story will start.
 
But if you didn't have stories on your previous level, and the new level doesn't contain them as well, please reach out to our technical support team.
